Above is a little section of my System.map file to show the EIP value. If
I boot 1.3.15 this does not happen. Boot 1.3.17 and it happens again. I
use gcc 2.7.0, libc 5.2.5, latest ld.so/binutils/etc. Kernel and netstat
binary compiled in elf. netstat is from latest 1.3.6 net-tools beta.
Hope I gave enough information.
